Here's why:
* Mood refers to the overall feeling or atmosphere that a piece of writing evokes in the reader. It's created through a combination of literary devices such as imagery, diction, and tone.
* Tone, on the other hand, refers to the author's attitude towards the subject matter.
While tone is a part of creating mood, it's important to distinguish between the two. The mood is the effect on the reader, while the tone is the author's intention.
For example, a poem might have a somber tone but evoke a feeling of hope in the reader. This would mean the tone is somber, but the mood is hopeful.
